Description

Garde-corps monobloc pour tour d'étaiement, et tour d'étaiement le comportant  Monobloc Guardrail for Shoring Tower, and Shoring Tower Including It
L'invention concerne le domaine des tours d'étaiement pour la construction d'immeubles ou d'édifices. Plus précisément elle concerne un garde-corps destiné à être intégré à une telle tour pour empêcher la chute du personnel travaillant aux divers étages de la tour, notamment lors de son montage et de son démontage. The invention relates to the field of shoring towers for the construction of buildings or buildings. More specifically it relates to a railing intended to be integrated in such a tower to prevent the fall of staff working on the various floors of the tower, including during its assembly and disassembly.
Les règles de montage et de démontage des structures métalliques utilisées sur les chantiers de construction de bâtiments (échafaudages et tours d'étaiement) imposent généralement que ces opérations doivent être effectuées avec une sécurité optimale pour le personnel. En particulier, un opérateur ne peut accéder à un niveau supérieur de la structure que lorsque ce niveau a été sécurisé par la présence d'une ceinture d'éléments généralement tubulaires appelés « garde-corps ».  The rules for assembling and dismantling metal structures used on building construction sites (scaffolding and shoring towers) generally dictate that these operations must be carried out with the utmost safety for the personnel. In particular, an operator can access a higher level of the structure only when this level has been secured by the presence of a belt of generally tubular elements called "guardrails".
Dans le cas de structures métalliques de type multidirectionnel, l'érection de la structure s'effectue en accrochant à des poteaux, munis à cet effet de pièces d'accueil de type rosaces, coupelles ou pontets, des lisses horizontales dont les extrémités sont pourvues de pièces adaptées à coopérer avec lesdites pièces d'accueil, à savoir des pinces et clavettes, ou des platines d'accrochage. Le montage et le démontage de ces structures ne peuvent être effectués véritablement en toute sécurité que si les garde- corps à assembler sont d'un type monobloc, c'est-à-dire non constitués d'une association d'éléments initialement séparés (lisses, sous-lisses, entretoises). Ce type monobloc permet de monter les garde-corps rapidement, sans nécessiter la présence d'un opérateur à leur niveau alors que ce niveau n'est pas encore totalement sécurisé, et de leur conférer une rigidité satisfaisante, sans risque qu'une mauvaise exécution de la connexion d'éléments entre eux ne conduise à leur désassemblage.  In the case of metal structures of multidirectional type, the erection of the structure is effected by hanging on poles, provided for this purpose with rosettes, cups or bridges, horizontal rails whose ends are provided with pieces adapted to cooperate with said home parts, namely clamps and keys, or mounting plates. The assembly and disassembly of these structures can be made truly safe only if the railings to be assembled are of a monobloc type, that is to say not consisting of an association of initially separated elements ( smooth, sub-smooth, spacers). This monobloc type makes it possible to mount the railings quickly, without requiring the presence of an operator at their level while this level is not yet completely secure, and to give them a satisfactory rigidity, without risk of poor execution the connection of elements between them does not lead to their disassembly.
Cependant, si on veut utiliser des poteaux à rosace, habituellement destinés à l'érection d'échafaudages, pour la construction de garde-corps, on ne peut utiliser de garde-corps monoblocs, dans les configurations connues jusqu'ici. On est donc obligé de recourir à des garde-corps multiéléments, avec les inconvénients que l'on vient de signaler et qui obligent donc le personnel à travailler en insécurité tant que le garde-corps n'est pas assemblé de manière complète et sûre. Pourtant, l'utilisation de tels poteaux à rosace pour des tours d'étaiement aurait pour avantage de réduire le nombre d'éléments de structures qu'un fabricant devrait avoir à son catalogue pour satisfaire tous les besoins des utilisateurs, et de simplifier la gestion par l'utilisateur de son stock d'éléments de structure.  However, if one wants to use rosette posts, usually intended for the erection of scaffolding, for the construction of railings, one can not use monobloc railings, in the configurations known hitherto. It is therefore necessary to resort to multi-element railings, with the disadvantages that have just been pointed out and which therefore require staff to work insecure as the railing is not assembled in a complete and safe manner. However, the use of such rosette poles for shoring towers would have the advantage of reducing the number of structural elements that a manufacturer should have in his catalog to meet all user needs, and to simplify management. by the user of his stock of structural elements.
Le but de l'invention est de proposer un nouveau type de garde-corps monobloc pour tour d'étaiement, utilisable dans une structure dont les poteaux multidirectionnels seraient également utilisables dans un échafaudage dont les poteaux porteraient des rosaces pour la fixation des éléments qui devraient leur être liés. Ce garde-corps devrait aussi, avantageusement, pouvoir être utilisés avec des poteaux multidirectionnels portant d'autres dispositifs de fixation que des rosaces. The object of the invention is to propose a new type of guard rail monobloc for propping tower, usable in a structure whose multidirectional poles could also be used in a scaffolding whose poles would carry rosettes for fixing the elements that should be linked to them. This railing should also advantageously be used with multidirectional posts carrying other fasteners that rosettes.
A cet effet, l'invention a pour objet un garde-corps monobloc pour tour d'étaiement, caractérisé en ce qu'il est constitué par un cadre comportant les éléments tubulaires suivants:  For this purpose, the subject of the invention is a monobloc guardrail for a shoring tower, characterized in that it consists of a frame comprising the following tubular elements:
- une lisse inférieure horizontale qui porte à ses deux extrémités des éléments de fixation adaptés à la fixation de la lisse sur les poteaux verticaux de reprise de charge de la tour d'étaiement à laquelle le garde-corps doit s'intégrer ;  - A horizontal lower rail which carries at both ends of the fasteners adapted to the attachment of the rail on the vertical load-bearing posts of the shoring tower to which the railing is to be integrated;
- un montant tubulaire vertical qui a son extrémité inférieure soudée à une des extrémités de la lisse inférieure et comporte au moins un élément de fixation adapté à la fixation de la lisse sur les poteaux verticaux de reprise de charge de la tour d'étaiement à laquelle le garde-corps doit s'intégrer ;  a vertical tubular upright which has its lower end welded to one of the ends of the lower rail and comprises at least one fastening element adapted for fastening the rail to the vertical load-bearing posts of the shoring tower to which the guardrail must integrate;
- un tube formant diagonale reliant le montant vertical à l'autre des extrémités de la lisse inférieure ;  a diagonal tube connecting the vertical upright to the other end of the lower rail;
- un tube coudé à 90°, dont une partie horizontale est raccordée au tube vertical à proximité de son extrémité supérieure, et dont la partie verticale est connectée, à son extrémité inférieure, à l'extrémité de la diagonale qui est elle-même raccordée à la lisse inférieure.  - a 90 ° elbow tube, a horizontal portion of which is connected to the vertical tube near its upper end, and whose vertical part is connected at its lower end to the end of the diagonal which is itself connected at the lower rail.
Il peut comporter également une échelle d'accès fixée dans sa partie inférieure à la lisse inférieure ou au tube formant diagonale, et dans sa partie supérieure à la partie horizontale du tube coudé, et étant également soudée à la diagonale.  It may also include an access ladder fixed in its lower part to the lower rail or the diagonal tube, and in its upper part to the horizontal part of the elbow tube, and being also welded diagonally.
L'échelle d'accès peut être placée en position centrée à l'intérieur de la structure du garde-corps.  The access ladder can be placed in a centered position inside the railing structure.
Les éléments de fixation de la lisse inférieure et du montant tubulaire vertical peuvent être constitués par des pinces et des clavettes.  The fastening elements of the lower rail and the vertical tubular upright can be constituted by clamps and keys.
Les éléments de fixation de la lisse inférieure et du montant tubulaire vertical peuvent être constitués par des coupelles et des platines.  The fastening elements of the lower rail and the vertical tubular upright can be constituted by cups and plates.
Le garde-corps monobloc peut comporter, dans sa partie supérieure, une lisse horizontale de rehaussement, qui est déportée par rapport au plan du reste du garde- corps.  The one-piece railing may comprise, in its upper part, a horizontal raising bar, which is offset from the plane of the rest of the guardrail.
La partie horizontale du tube coudé peut être logée au fond d'au moins deux réceptacles en forme de V, destinés à recevoir la lisse inférieure d'un garde-corps de l'étage immédiatement supérieur de la tour. La lisse de rehaussement peut être fixée sur des faces externes des réceptacles. The horizontal portion of the bent tube may be housed at the bottom of at least two V-shaped receptacles for receiving the lower rail of a railing of the next higher stage of the tower. The raising bar can be fixed on external faces of the receptacles.
L'invention de rehaussement pour objet une tour d'étaiement, caractérisée en ce qu'elle comporte des poteaux multidirectionnels d'échafaudage, des garde-corps du type précédent, et des plateaux de montage disposés aux divers étages de la tour.  The object of the invention is to enhance a shoring tower, characterized in that it comprises multidirectional scaffolding posts, guardrails of the preceding type, and mounting plates arranged at the various stages of the tower.
Lesdits garde-corps peuvent être dépourvus de lisse de rehaussement, et lesdits plateaux de montage sont fixés sur les garde-corps au moyen de crochets de surbaissement.  Said railings may be devoid of raising bar, and said mounting plates are fixed on the guardrails by means of lowering hooks.
Comme on l'aura compris, l'invention consiste à prévoir un garde-corps pour tour d'étaiement compatible avec l'utilisation de poteaux standards d'échafaudage. Il est constitué par une lisse inférieure tubulaire, un montant tubulaire vertical fixé, par exemple par soudage, à une extrémité de la lisse inférieure, une diagonale tubulaire reliant la lisse et le montant vertical, et un tube de fermeture coudé à 90° constituant l'élément fonctionnel du garde-corps et reliant l'extrémité supérieure du montant vertical à l'autre extrémité de la lisse inférieure. Des éléments de fixation permettent de relier la lisse inférieure et le montant vertical à des poteaux standards d'échafaudage munis eux- mêmes d'éléments de fixation correspondants.  As will be understood, the invention consists in providing a railing for a shoring tower compatible with the use of standard scaffolding posts. It is constituted by a tubular lower rail, a vertical tubular upright fixed, for example by welding, at one end of the lower rail, a tubular diagonal connecting the rail and the vertical upright, and a 90 ° bent closure tube constituting the functional element of the railing and connecting the upper end of the vertical upright to the other end of the lower rail. Fasteners allow the lower and the upright to be connected to standard scaffold posts which themselves have corresponding fasteners.
La tour d'étaiement également objet de l'invention est constituée de garde-corps de ce type, et de poteaux et d'accessoires d'échafaudage standards. Elle permet de reprendre des charges importantes, et surtout elle peut être montée et démontée en respectant les règles de sécurité les plus strictes en vigueur.  The shoring tower also object of the invention consists of railings of this type, and standard poles and scaffolding accessories. It allows to take back important loads, and especially it can be assembled and dismounted respecting the most stringent security rules in force.
Elle permet également d'utiliser des poteaux d'échafaudage de type standard pour constituer une tour d'étaiement. Cela a notamment pour avantage de diminuer le nombre de catégories de pièces qu'une entreprise du bâtiment doit posséder, sachant que ces poteaux pourront être utilisés aussi bien pour construire des échafaudages que pour construire des tours d'étaiement. La gestion du stock de matériel de l'entreprise est donc ainsi simplifiée. De même les fabricants de ces matériels et loueurs peuvent diminuer le nombre de pièces qu'ils doivent avoir à leur catalogue pour satisfaire tous les besoins de leurs clients.  It also makes it possible to use standard-type scaffolding posts to form a shoring tower. This has the advantage of reducing the number of categories of parts that a building company must have, knowing that these poles can be used both for scaffolding and for building shoring towers. The management of the equipment stock of the company is thus simplified. Similarly manufacturers of these materials and rental companies can reduce the number of parts they must have in their catalog to meet all the needs of their customers.

Le garde-corps 1 se compose des éléments suivants, qui sont assemblés les uns aux autres de façon rigide et indémontable, par exemple par soudage. - Figure 1 1 is a view similar to Figure 5 for the variant of Figure 7. The guardrail 1 consists of the following elements, which are joined to each other rigidly and indémontable, for example by welding.
Une lisse inférieure 2 constitue l'élément principal de la structure métallique horizontale. Il s'agit d'un tube métallique horizontal qui porte à ses deux extrémités des éléments de fixation 3, 4 d'un type quelconque (et, à ce titre, représentés d'une façon symbolique sur la figure 1 ) pourvu qu'il soit adapté à la fixation de la lisse sur les poteaux verticaux de reprise de charge de la tour d'étaiement à laquelle le garde-corps 1 doit s'intégrer. Ces éléments de fixation 3, 4 constituent des points d'accrochage bas aux poteaux d'échafaudage de la tour pour le garde-corps 1 . Typiquement, cette lisse inférieure 2 est en acier et a un diamètre et une épaisseur de paroi suffisants pour reprendre les efforts auxquels elle est soumise : par exemple 48,3 mm de diamètre et 3,2 mm d'épaisseur.  A lower rail 2 is the main element of the horizontal metal structure. It is a horizontal metal tube which carries at its two ends fastening elements 3, 4 of any type (and, as such, shown symbolically in FIG. 1) provided that it is adapted to the attachment of the rail on the vertical load-bearing posts of the shoring tower to which the guard rail 1 must integrate. These fastening elements 3, 4 are low attachment points to the scaffolding posts of the tower for the guardrail 1. Typically, this lower rail 2 is made of steel and has a diameter and a sufficient wall thickness to absorb the forces to which it is subjected: for example 48.3 mm in diameter and 3.2 mm in thickness.
Un montant tubulaire vertical 5 a son extrémité inférieure 6 soudée à la lisse inférieure 2. Typiquement, il a une longueur de 0,94 m ;  A vertical tubular upright 5 has its lower end 6 welded to the lower rail 2. Typically, it has a length of 0.94 m;
Un tube formant diagonale 7 est présent. Dans l'exemple représenté sur la figure 1 , il relie un des points d'accrochage bas du garde-corps 1 (en l'espèce l'élément de fixation 4) à un point d'accrochage haut matérialisé par un élément de fixation 8 identique aux autres éléments de fixation 3, 4, et qui assure la fixation du garde-corps 1 au poteau d'échafaudage vertical de reprise de charge immédiatement supérieur à celui auquel l'autre point d'accrochage bas du garde-corps 1 est relié (en l'espèce l'élément de fixation 3). Typiquement, ce point d'accrochage haut est situé à 50 cm du point d'accrochage bas qu'il surplombe, de façon à être compatible avec l'utilisation de poteaux d'échafaudage à rosaces dont les rosaces sont distantes de 50 cm. La diagonale 7 forme donc, dans l'exemple représenté, un angle de 30 ° avec la lisse inférieure 2. Mais cet angle pourrait être différent, par exemple de 45° de sorte que la diagonale 7 connecterait l'extrémité supérieure 9 du tube vertical 5 audit point d'accrochage bas du garde-corps 1 matérialisé par l'élément de fixation 4. Cette diagonale 7 permet de reprendre les efforts latéraux exercés sur le garde-corps 1 . A diagonal tube 7 is present. In the example shown in Figure 1, it connects one of the lower attachment points of the railing 1 (in this case the fastening element 4) to a high attachment point materialized by a fastener 8 identical to the other fastening elements 3, 4, which ensures the fixing of the guardrail 1 to the vertical load-bearing scaffolding post immediately above that to which the other lower attachment point of the railing 1 is connected. (in this case the fastening element 3). Typically, this high attachment point is located 50 cm from the low hanging point that it overhangs, so as to be compatible with the use of scaffolding posts to rosettes whose rosettes are 50 cm apart. The diagonal 7 thus forms, in the example shown, an angle of 30 ° with the lower rail 2. But this angle could be different, for example 45 ° so that the diagonal 7 would connect the upper end 9 of the vertical tube 5 at said low attachment point of the railing 1 materialized by the fastening element 4. This diagonal 7 allows to take up the lateral forces exerted on the railing 1.
Les trois éléments 2, 5 et 7 qui viennent d'être décrits constituent un triangle de contreventement qui est la base du garde-corps 1 selon l'invention.  The three elements 2, 5 and 7 which have just been described constitute a bracing triangle which is the base of the railing 1 according to the invention.
Selon l'invention, le garde-corps 1 comporte également un tube coudé à 90 ° 10. La partie horizontale 1 1 du tube 10 est raccordée au tube vertical 5 à proximité de son extrémité supérieure 9, typiquement à une distance de 90 cm de la lisse inférieure 2. La partie verticale 12 du tube coudé 10 est connecté, à son extrémité inférieure 13, à l'extrémité de la diagonale 7 qui est elle-même raccordée à la lisse inférieure 2. C'est ce tube coudé 10 qui assure la fonction garde-corps. Il peut être d'un diamètre plus réduit que ceux de la lisse inférieure 2, du tube vertical 5 et de la diagonale 7, car il ne participe que dans une moindre mesure à la reprise des efforts exercés sur le garde-corps 1 .  According to the invention, the railing 1 also comprises a tube bent at 90 ° 10. The horizontal part 1 1 of the tube 10 is connected to the vertical tube 5 near its upper end 9, typically at a distance of 90 cm from the lower rail 2. The vertical portion 12 of the bent tube 10 is connected at its lower end 13 to the end of the diagonal 7 which is itself connected to the lower rail 2. It is this bent tube 10 which ensures the guardrail function. It may be smaller in diameter than those of the lower rail 2, the vertical tube 5 and the diagonal 7, because it participates only to a lesser extent in the recovery of the forces exerted on the railing 1.
De façon optionnelle mais préférée, le garde-corps 1 comporte également, lui étant intégrée de construction, une échelle d'accès 14 assurant une fonction d'accès du personnel aux différents niveaux de la tour. Dans l'exemple représenté, elle est soudée dans sa partie inférieure à la diagonale 7 et à la lisse inférieure 2, et dans sa partie supérieure à la partie horizontale 1 1 du tube coudé 10. la lisse 2 et les barreaux 15, 16 de l'échelle d'accès 14 sont typiquement séparés chacun de 30 cm, distance imposée par les réglementations de certains pays. La lisse inférieure 2 peut être utilisée comme un barreau supplémentaire par le personnel. L'échelle d'accès 14 est également soudée à la diagonale 7, ce qui permet de la renforcer. De façon générale, avantageusement la présence de l'échelle d'accès 14 renforce la rigidité de l'ensemble du garde-corps 1 . L'échelle d'accès 14 est, de préférence, placée en position centrée à l'intérieur de la structure du garde-corps 1 , de manière à assurer qu'elle sera toujours alignée sur les échelles d'accès des garde-corps situés au niveau inférieur et au niveau supérieur de la tour, dont le placement est également centré. Cela permet aussi la continuité de l'alignement de l'échelle si les garde-corps sont inversés lors du montage. On a ainsi une parfaite continuité entre les échelles d'accès 14 de tous les garde-corps 1 de la tour, et le personnel peut accéder aux différents étages de la tour selon un trajet rectiligne. L'intégration de l'échelle d'accès 14 au garde-corps 1 permet également d'éviter de devoir rapporter une échelle d'accès sur le garde-corps 1 pendant le montage, qui est ainsi plus rapide et plus simple, et d'éviter d'avoir à gérer un stock d'échelles d'accès séparées. Outre sa fonction de garde-corps, le garde-corps 1 sert aussi de support pour les plateaux de la tour d'étaiement (voir la figure 5). Optionally but preferably, the guardrail 1 also comprises, being built-in, an access ladder 14 providing a personnel access function at different levels of the tower. In the example shown, it is welded in its lower part to the diagonal 7 and the lower rail 2, and in its upper part to the horizontal part 1 1 of the elbow tube 10. the rail 2 and the bars 15, 16 of the access ladder 14 are typically separated by 30 cm each, a distance imposed by the regulations of certain countries. The lower rail 2 can be used as an additional bar by the staff. The access ladder 14 is also welded to the diagonal 7, which makes it possible to reinforce it. In general, advantageously the presence of the access ladder 14 reinforces the rigidity of the whole of the guardrail 1. The access ladder 14 is preferably placed in a centered position inside the structure of the railing 1, so as to ensure that it will always be aligned with the access ladders of the railings located at the lower level and at the top level of the tower, whose placement is also centered. This also allows the continuity of the scale alignment if the guardrails are reversed during assembly. There is thus a perfect continuity between the access ladders 14 of all guardrails 1 of the tower, and the staff can access the different floors of the tower in a straight path. The integration of the access ladder 14 with the railing 1 also makes it possible to avoid having to report an access ladder on the railing 1 during the assembly, which is thus faster and simpler, and avoid having to manage a stock of separate access ladders. In addition to its guardrail function, guardrail 1 also serves as support for the shoring tower decks (see Figure 5).
Le garde-corps 17 selon représenté sur la figure 2 est un autre exemple de mise en œuvre de l'invention. Il comporte les mêmes éléments principaux que l'exemple de la figure 1 , qui sont référencés de la même façon. On a ici représenté de façon précise les dispositifs les trois éléments de fixation précédemment décrits, qui sont ici d'un type connu à pince 18 et clavette 19 coopérant avec une rosace du poteau correspondant de la tour, la clavette 19 étant enfoncée dans l'une des perforations de la rosace.  The railing 17 as shown in Figure 2 is another example of implementation of the invention. It has the same main elements as the example of Figure 1, which are referenced in the same way. The three previously described fastening elements, which are here of a known type with clamp 18 and key 19 cooperating with a rosette of the corresponding column of the tower, are shown here in a precise manner, the key 19 being inserted into the latch. one of the perforations of the rosace.
Ce garde-corps 17 comporte en plus, dans sa partie supérieure, selon une réalisation particulière, une lisse horizontale de rehaussement 20, qui est déportée par rapport au plan du reste du garde-corps 17. Elle permet d'assurer une protection à plus de 1 m de hauteur par rapport à la lisse inférieure 2 sans forcément causer une augmentation de poids très significative du garde-corps 17 puisque, comme elle ne participe pas à la rigidité de l'ensemble, elle peut avoir un diamètre et une épaisseur inférieurs à ceux des autres éléments du garde-corps 17.  This railing 17 further comprises, in its upper part, according to a particular embodiment, a horizontal raising bar 20, which is offset relative to the plane of the rest of the railing 17. It provides protection to more 1 m high relative to the lower rail 2 without necessarily causing a significant increase in weight of the railing 17 since, as it does not participate in the rigidity of the assembly, it may have a lower diameter and thickness to those of the other elements of the railing 17.
La partie horizontale 1 1 du tube coudé 10 comporte, soudée sur elle au moins deux réceptacles 21 , 22 en forme de V, représentés sur la figure 3. Ces réceptacles 21 , 22 sont destinés à recevoir la lisse inférieure 23 d'un garde-corps de l'étage immédiatement supérieur de la tour, et le contour de la section de cette lisse 23 est représenté en pointillés sur la figure 3. Cette lisse 23 peut donc, lors du montage de la tour, être maintenue au niveau désiré tant qu'elle n'a pas été complètement solidarisée aux poteaux qu'elle doit relier. On voit sur la figure 3 (et aussi sur la figure 2) que le tube coudé 10 a, au moins dans sa partie horizontale 1 1 , un diamètre relativement faible (par exemple 27 ou 33,7 mm) qui lui permet de se loger au fond du réceptacle 22, alors que la lisse inférieure 23 du garde-corps supérieur a un diamètre normalement égal à celui de la lisse 2 correspondante du garde-corps 17. De ce fait, la lisse 23 repose dans le réceptacle en V 22 à un niveau supérieur à celui de la partie horizontale 1 1 du tube coudé 10. Leurs axes longitudinaux sont espacés par exemple d'environ 10 cm pour que la distance entre les lisses inférieures 2 et 23 de deux étages successifs de la tour, compte tenu des exemples de dimensions que l'on a donnés, soit de l'ordre de 1 m comme c'est souvent le cas sur les tours d'étaiement habituelles.  The horizontal part 1 1 of the elbow tube 10 comprises, welded on it at least two receptacles 21, 22 V-shaped, shown in Figure 3. These receptacles 21, 22 are intended to receive the lower rail 23 of a guard- body of the immediately higher stage of the tower, and the contour of the section of this rail 23 is shown in dashed lines in FIG. 3. This rail 23 can therefore, when mounting the tower, be maintained at the desired level as long as it has not been fully secured to the posts it must connect. It can be seen in FIG. 3 (and also in FIG. 2) that the bent tube 10 has, at least in its horizontal portion 11, a relatively small diameter (for example 27 or 33.7 mm) which enables it to be lodged. at the bottom of the receptacle 22, while the lower rail 23 of the upper railing has a diameter normally equal to that of the corresponding rail 2 of the railing 17. As a result, the rail 23 rests in the V receptacle 22 to a level higher than that of the horizontal portion 1 1 of the elbow tube 10. Their longitudinal axes are spaced for example about 10 cm so that the distance between the lower rails 2 and 23 of two successive stages of the tower, taking into account the examples of dimensions that have been given, ie of the order of 1 m as is often the case on the usual shoring towers.
Quant à la lisse de rehaussement 20, si elle est présente, elle est avantageusement soudée sur des faces externes des réceptacles 21 , 22, par exemple, comme représenté, au niveau de leurs extrémités supérieures.  As for the raising arm 20, if it is present, it is advantageously welded to external faces of the receptacles 21, 22, for example, as shown, at their upper ends.
Avantageusement, lorsque le garde-corps 1 ne comporte pas de lisse de rehaussement 20, on peut aussi surbaisser les plateaux de montage 32 en les fixant à leurs lisses inférieures au moyen de crochets de surbaissement qui leur sont solidaires. Ces crochets de surbaissement, c'est-à-dire dont la partie permettant d'accrocher le plateau 32 sur une lisse est située à une altitude supérieure à celle de la surface du plateau 32, permettent de placer la surface du plateau 32 à une distance de 1 m des lisses supérieures 1 1 des garde-corps qui lui sont les plus proches de part et d'autre de lui. Advantageously, when the guardrail 1 does not have a raising arm 20, it is also possible to lower the mounting plates 32 by fixing them to their lower rails by means of lowering hooks which are integral with them. These lowering hooks, that is to say the part of which to hang the plate 32 on a rail is located at an altitude greater than that of the surface of the plate 32, allow to place the surface of the plate 32 to a distance of 1 m from the upper rails 1 1 of the railings that are closest to him on both sides of him.
La forme sensiblement en V des réceptacles 21 , 22, qui ont une ouverture, par exemple, de 50 mm, donc un peu supérieure au diamètre des lisses 2, 23, permet de guider la lisse 23 qu'ils reçoivent jusqu'à sa position définitive lors du montage de la tour, avant sa solidarisation aux poteaux.  The substantially V-shaped receptacles 21, 22, which have an opening, for example, 50 mm, so slightly greater than the diameter of the rails 2, 23, to guide the beam 23 they receive to its position final assembly of the tower, before its attachment to the posts.
La figure 4 montre un autre exemple de garde-corps 24 selon l'invention. Il ne diffère du garde-corps 17 de la figure 2 qu'en ce que les organes de connexion 25, 26, 27 aux poteaux de la tour sont d'un type différent, dit « Cuplock », connu en lui-même, comportant chacun une coupelle et une platine et destinés à coopérer avec des organes de connexion placés sur les poteaux d'échafaudage de la tour d'étaiement, constitués par des coupelles de connexion. Tout ce qui a été dit sur les autres parties du garde-corps 17 de la figure 2 est également valable pour les autres parties du garde-corps 24 de la figure 4.  Figure 4 shows another example of railing 24 according to the invention. It differs from the railing 17 of FIG. 2 only in that the connecting members 25, 26, 27 at the posts of the tower are of a different type, called "Cuplock", known in itself, comprising each a cup and a plate and intended to cooperate with connecting members placed on the scaffolding posts of the shoring tower, constituted by connecting cups. All that has been said about the other parts of the railing 17 of FIG. 2 is equally valid for the other parts of the railing 24 of FIG. 4.
La figure 5 montre une tour d'étaiement 28, réalisée à partir de poteaux 29 standards multidirectionnels d'échafaudage, munis de rosaces 30 espacées d'environ 50 cm, et comportant des garde-corps du type 17 de celui de la figure 2 fixés aux rosaces 30 par les moyens de connexion à pince 18 et clavette 19. Des vérins 31 placés aux quatre extrémités inférieures de la tour 28 permettent, comme il est connu, d'assurer la stabilité et la verticalité de la tour 28. On voit également sur la figure 5 les plateaux de montage 32 classiquement disposés aux divers étages de la tour 28 et qui comportent des plateaux à trappe d'accès 33 permettant l'accès du personnel auxdits étages.  FIG. 5 shows a shoring tower 28, made from standard multidirectional scaffolding posts 29, provided with rosettes 30 spaced about 50 cm apart, and having guard rails of the type 17 of that of FIG. 2 fixed rosettes 30 by the clamp connection means 18 and key 19. Cylinders 31 placed at the four lower ends of the tower 28 allow, as is known, to ensure the stability and verticality of the tower 28. It is also seen in Figure 5 the mounting plates 32 conventionally arranged at the various floors of the tower 28 and which comprise trays access hatch 33 allowing access to the staff said floors.
Le montage de la tour 28 s'effectue de la façon suivante :  The mounting of the tower 28 is carried out as follows:
- on place au sol les quatre vérins 31 ;  the four cylinders 31 are placed on the ground;
- on met en place les quatre premiers poteaux standards 29 d'échafaudage sur les vérins 31 ;  the first four standard posts 29 of scaffolding are placed on the cylinders 31;
- on met en place trois garde-corps universels d'étaiement 17 selon l'invention entre les entre les premières et deuxièmes attaches desdits premiers poteaux 29, en laissant libre un côté de la tour pour permettre au personnel d'accéder à l'intérieur de la tour 28 depuis le sol. On ferme ce côté par une lisse standard 34 d'échafaudage sur le niveau de la première attache et sur le niveau de la troisième attache, pour assurer une bonne rigidité à la tour 28 à ce niveau ; - on met en place quatre garde-corps 17 selon l'invention en les fixant aux attaches suivantes des poteaux de la tour 28, puis on place un plateau de montage 32 sur les lisses inférieures de deux garde-corps opposés, de sorte que le monteur peut accéder à ce plateau en toute sécurité, puisqu'il est alors déjà entouré par quatre garde-corps 17 selon l'invention ; three universal guardrails 17 are placed in place according to the invention between the first and second fasteners of the said first posts 29, leaving one side of the tower free to allow the personnel access to the interior; from tower 28 from the ground. This side is closed by a standard scaffolding beam 34 on the level of the first fastener and the level of the third fastener, to provide good rigidity to the tower 28 at this level; - Four guardrails 17 according to the invention are fixed by attaching them to the following fasteners of the posts of the tower 28, then a mounting plate 32 is placed on the lower rails of two opposite guardrails, so that the editor can access this tray safely, since it is then already surrounded by four guardrails 17 according to the invention;
- puis les garde-corps et plateaux des étages suivants sont mis en place successivement de la même façon, jusqu'à obtention de la hauteur désirée pour la tour 28.  - Then the railings and trays of the following stages are implemented successively in the same way, until the desired height for the tower 28.
En variante, tel que représenté sur la figure 6, l'échelle d'accès 14 peut, dans sa partie inférieure, n'être soudée qu'à la diagonale 7. Cela simplifie et allège la construction du garde-corps 1 sans réellement dégrader les conditions de sécurité du personnel si la diagonale 7 est suffisamment résistante pour supporter les efforts qui lui seront imposés lors de l'utilisation de l'échelle d'accès 14 par le personnel. Ce sera le cas, dans la pratique, notamment lorsqu'on respecte les conditions dimensionnelles données en exemple dans la description, et qui respectent les réglementations en vigueur dans de nombreux pays. Cette variante permet également d'installer plus aisément les plateaux de montage 32.  Alternatively, as shown in Figure 6, the access ladder 14 may, in its lower part, be welded to the diagonal 7. This simplifies and reduces the construction of the railing 1 without actually degrade the safety conditions of the personnel if the diagonal 7 is strong enough to withstand the efforts that will be imposed upon the use of the access ladder 14 by the staff. This will be the case, in practice, especially when the dimensional conditions given as example in the description, and which comply with the regulations in force in many countries, are respected. This variant also makes it easier to install the mounting plates 32.
Le garde-corps selon l'invention peut s'adapter à tous les types de connexion de poteaux d'échafaudage. Il suffit d'adapter la configuration des éléments de fixation 3, 4 au type de poteau employé, comme on en a donné des exemples sur les figures 2, 4 et 5.  The railing according to the invention can be adapted to all types of scaffold pole connection. It suffices to adapt the configuration of the fixing elements 3, 4 to the type of post used, as has been given in FIGS. 2, 4 and 5.
Une autre forme de réalisation de l'invention est illustrée sur les figures 7 et 8. Elle est applicable aux variantes du garde-corps 1 , 17, 24 selon l'invention pour lesquelles l'accrochage à un autre garde-corps 1 , 17, 24 du même niveau s'effectue par un mouvement horizontal frontal, typiquement lorsque le dispositif d'accrochage est un dispositif à rosace et à pince à clavette 18. Ce garde-corps 1 est équipé d'un dispositif qui contraint l'opérateur à monter et démonter les garde-corps 1 à partir du niveau qui leur est inférieur, conformément à la réglementation généralement en vigueur relativement à la sécurité sur les chantiers.  Another embodiment of the invention is illustrated in Figures 7 and 8. It is applicable to the variants of the railing 1, 17, 24 according to the invention for which the attachment to another guard rail 1, 17 , 24 of the same level is effected by a frontal horizontal movement, typically when the attachment device is a device rosette and pincer key 18. This railing 1 is equipped with a device that forces the operator to install and dismount the guardrails 1 from the level below them, in accordance with the generally applicable regulations regarding site safety.
Ce dispositif est constitué d'une poignée basculante 35 articulée autour d'un axe de rotation 36 placé, de préférence, sensiblement au milieu de la lisse inférieure 2. cette poignée basculante 35 est prolongée à l'une de ses extrémités par une fourche 37, qui se positionne par simple gravité en cavalier sur la lisse supérieure 1 1 du garde-corps 1 du niveau inférieur. Pour mettre en place ou démonter le garde-corps 1 , l'opérateur doit manuellement basculer la poignée 35 en position horizontale, mais ce n'est possible qu'une fois que les plateaux de montage 32 ont été retirés, et ne font plus obstacle à ce basculement. Cela permet aux pinces à clavette 18 de glisser le long des rosaces, ce qui est le seul moyen de dégager le garde-corps 1 . This device consists of a tilting handle 35 articulated about an axis of rotation 36 placed, preferably, substantially in the middle of the lower rail 2. this tilting handle 35 is extended at one of its ends by a fork 37 which is positioned by simple gravity jumper on the top rail 1 1 of the railing 1 of the lower level. To set up or dismount the railing 1, the operator must manually tilt the handle 35 to the horizontal position, but this is possible only after the mounting plates 32 have been removed, and are no longer an obstacle. at this failover. This allows the key clips 18 to slide along the rosettes, which is the only way to clear the guardrail 1.
Pour faciliter la manutention et réduire les risques de pincement des doigts de l'opérateur, un décrochement 38 est ménagé sur la lisse supérieure 1 1 , à un emplacement destiné à faire face à la poignée 35 du garde-corps 1 du niveau supérieur.  To facilitate handling and reduce the risk of pinching the fingers of the operator, a recess 38 is provided on the top rail 1 1 at a location intended to face the handle 35 of the guardrail 1 of the upper level.
